In this work, the buckling behavior of the cross-ply laminated non-homogeneous orthotropic truncated conical shells in the large deformation under the uniform axial load is studied.
The overall behavior under uniform load of cold-formed steel C-sections assemblies was investigated.
The intention in this paper is to use the continuum approach and describe the analytical solutions that govern the simple bending, flexure, or bending under a uniform load, of an anisotropic elastic cylinder consisting of a single material of this type.
The instability regions are found and plotted for the plate under a tangent uniform load and a tangent concentrated force.
Golmakani and Rezatalab [1] suggested in their paper that the deflection of a simply supported nonlocal elastic plate under uniform load is not affected by the small length scale terms.
The plates considered for comparison are simply supported isosceles right triangular plate (Lim, 2016a), equilateral triangular plate (Lim, 2016b), square plate, and rectangular plate of aspect ratio 4 under uniform load and possess the dimensionless plate thickness of h/a = 0.2.

By submitting these elastic constants into closed-form solution, the response of simply supported sandwich panel under uniform load with small deflection is calculated which agrees well with 3D FEM analysis.
The nonlinear analysis indicates a good agreement for the load displacement with test results, although a slight overestimation in terms of the flexural strength was observed for beams under an analogous uniform load.
